Blue Moon 2015

Blue Moon 2015
Tonight’s moon is not going to look like this.

Tonight, July 31, there will be a blue moon. Many will go out and look at it. All will say it looks just like any other full moon. They will be right.

A “blue moon” is a full moon appearing a second time in a month. It’s a fairly rare occurrence happening once every 30 months or so.

The last blue moon was in August 2012. The next one will be in January 2018.

The moon has at times actually turned blue, it should be noted. This usually happens after a major volcanic eruption with the ash filtering the light reflected from the orb.

And the meaning of “blue moon” has changed slightly from when it came into use. It  originally meant the third full moon in a season that had four, understanding that seasons are considered to be three months long and hence typically have but three full moons.

Anyway, here is some music for you:
